Answer:
y= -x(x+2)(x-1)².
Step-by-step explanation:
the graph and equation is in the attached picture.
The zeros of function y are: -2; 0 and 1 - they help to determine the required equation.
D = # of dimes
n= # of nickles
d + n = 34 so d = 34 - n
.10d + .05n = 2.05
substitute d = 34 - n into .10d + .05n = 2.05
.10d + .05n = 2.05
.10( 34 - n) + .05n = 2.05
3.4 - .1n + .05n = 2.05
-.05n = -1.35
n = 27
d = 34 - n
d = 34 - 27
d = 7
answer
<span>she received 7 dimes and 27 nickels</span>
The answer to your question is c
My answer would probably be 10 because draw a line between the equal sign and the opposite of + is subtract and put it by the 17 so x=10
